This page is for users of the Working Draft;
If you are using the Recommendation,
please use this version instead.

This page is meant to be a tool for readers and parser implementers of
XQuery 1.0
(http://www.w3.org/TR/2005/WD-xquery-20051103/).
It allows them to type in an expression, and then view the parse tree, or else
obtain an error if it is syntactically incorrect.
The results should not be used as an absolute reference, and may flag legal
syntax or errors not intended by the drafts.
However, the parser used was generated by processing the
XML representation of the grammar, which
is also used to produce the EBNF productions in the XPath and XQuery
drafts. This parser is also used by the working groups to validate the
integrity of the grammar. Implementers may wish to download the XPath
2.0/XQuery 1.0 Parser Build, xgrammar.zip,
if they are interested in the parser production, and more details of
this process.

Type in a XQuery 1.0 expression then click on the button:
